A raging snow storm creates the coldest kind of danger for two kids in this riveting tale of historical fiction, part of the Survivor series. Haydn Sinclair hates absolutely everything about his aunt and uncle's primitive Rocky Mountain ranch. He'd much rather be in a great city than stuck on the countryside. Haydn's cousin Maggie hates the thought of having her rich and spoiled cousin visiting for four long months. She'd be happier if he wasn't around. When Maggie's father is injured and she and Haydn are left alone, they argue, and Haydn sets off on foot for the train station miles away. The next day Maggie learns that Haydn never made it to town, and she must search for him despite the blizzard that is raging outside. But even if she can find him, will they be able to survive freezing nights, vicious winds, and the constant threat of snow slides?
